There’s an opening.

There was a single Servant who saw that moment as an opening. Rider’s body reacted to the killing intent being directed at him then. But the blood of the homunculi was blocking his vision. Passing through a gap between the corpses, an arrow was shot at the nape of Rider’s neck.

“…Kuh!!”

Though his reaction was an instant delayed, Rider of Red’s quick‐wittedness and agility allowed him to strike down the arrow with his sword. However, he couldn’t completely knock it away and even with its trajectory change the arrow still grazed his neck.

Vivid red blood dripped down his neck. His surprise at being wounded was turned into joy instead of humiliation for Rider.
